What is image processing? It is converting a graphic or photo in digital form and performing some steps and procedures so that the said photo/graphic can be enhanced or you can extract information from it. In image processing, the input is a graphic/photo (a video frame or photograph) and the output is that same graphic/photo or certain characters associated with it. The procedure involves a signal dispensation. The images are two dimensional signals where set signal processing methods are applied to it.
In many businesses, image processing applications are particularly crucial. In rapidly growing technologies today, such as computer science and engineering, processing is necessary in core research. There are 3 basic steps:
The image is imported using an optical scanner or digital photography
Applying graphic/photo enhancement, data compression and spotting pattern techniques to analyze and manipulate the graphic/photo
Based on image analysis, the altered graphic or report is produced as output
What is the purpose of image processing? They are divided in 5 groups:
Visualization- objects that are not visible can be observed
Image sharpening and restoration- so that a better graphic/photo can be created
Image retrieval- searching for a desired image
Image recognition- the objects in a graphic/photo can be distinguished
Types of processing an image
There are 2 methods typically used:
Analog
Digital
In analog processing, visual techniques of processing an image are applied to hard copy photographs and print outs. Different fundamentals of interpretation are used by analysts. Knowledge of the analyst combined with the area that needs study comprise the total processing output of the image. Association in visual techniques is also incorporated. An analyst therefore creates a well-designed and processed graphics/photo by combining his/her personal knowledge and collateral data. Computers are used to manipulate digital graphics/photo using digital processing techniques. Satellite platform sensors contain raw data with deficiencies. The raw image has to therefore undergo several phases of editing and processing to overcome flaws and obtain original information.
All types of data have to undergo three general phases of digital technique:
Pre-processing
Enhancement and display
Information extraction
Systems used to manipulate multi- dimensional signals may be simple digital circuits to more advanced parallel computers. Modern digital technology manipulates images with 3 goals in consideration:
Image processing
Image analysis
Image understanding
Graphic/photo processing algorithms are developed, specifically to enhance pertinent applications, but what has yet to be fully explored is real time performance. Real world devices such as digital cellphone cameras, personal digital assistants, smartphones, portable media players, vision- assisted intelligent robots, high definition televisions, spectral imaging systems and other embedded video or photo processing systems critically integrate the real time aspect. Developments have been overwhelming so far and graphic/photo processing remains to be an indispensable aspect of digital publishing.
If you have the time, you can find exciting and challenging to self- study about image processing. However, it is a meticulous process that requires patience, and you can’t risk producing amateur results for your product. Packaging is a big thing when you sell digital products, especially on the Internet. Outsourcing your digital publishing needs is oftentimes the best alternative wherein you save time and money while obtaining the best processing and digital graphics result.
